Step by step

In the order most owners do them. Each step says where it happens and links to the official page.

  1. With the state

    Check your name is free

    Search the Wisconsin Department of Financial Institutions's business records to check no business already uses your name, or one too close to it. An LLC's name must also end with "LLC" or a similar ending.

  2. Your records

    Choose a registered agent

    Every LLC and corporation in Wisconsin needs a registered agent: a person or company with a street address in Wisconsin who receives legal papers and state notices for it. You can be your own, or pay a registered agent service.

  3. With the state

    File your Articles of Organization

    File them with the Wisconsin Department of Financial Institutions, online or by mail. The state's fee is $130 online ($170 on paper); expedited service costs $100 more and is optional. Once they're filed, your business exists.

  4. Your records

    Write an operating agreement

    It sets out who owns the LLC, how decisions are made and what happens if someone leaves. It isn't filed with the state: keep it with your records. A lawyer can help you write one.

  5. With the IRS

    Get an EIN from the IRS

    An Employer Identification Number is your business's tax number, for taxes, hiring and a bank account. Apply once your Articles of Organization are filed. It's free from the IRS: with a Social Security number or ITIN, you can apply on the IRS's own site and get it at once. Watch out for look-alike sites that charge for it.

    Apply for an EIN on IRS.gov (opens the official site)

  6. With the state

    Register for state taxes

    If you'll sell taxable goods or services, or hire employees, register with the Wisconsin Department of Revenue; the Business Tax Registration fee is $20 and covers two years ($10 to renew). Employers also register with the Department of Workforce Development for unemployment insurance. The Wisconsin One Stop Business Portal can register a new business with the Department of Financial Institutions, the Department of Revenue and the Department of Workforce Development together.

  7. City or county

    Check local licenses and permits

    Depending on what it does, your business may need licenses or permits from a Wisconsin state agency, and your city, village, town or county may have its own requirements, such as licenses, permits or zoning approval.

    Find your local requirements (opens the official site)

  8. Your records

    Open a business bank account

    Keep the business's money apart from your own: it keeps your records clear at tax time, and keeps the LLC separate from you. Banks usually ask for your filed Articles of Organization and your EIN.

  9. With the state

    Put the yearly report in your calendar

    Every LLC in Wisconsin files an annual report with the Department of Financial Institutions each year after the year it's formed, by the end of the calendar quarter in which it was formed (March 31, June 30, September 30 or December 31). The fee is $25 online ($40 on paper). The state can administratively dissolve an LLC whose report is more than a year overdue.
